Cython in CodinGame

As a python programmer I would like Cython so that I can compete (better) in the more computationally challenging challenges.

At the time of writing this I am 80 in Ultimate Tic Tac Toe with the top Python bot sitting at 68. This is a game that relies on significant simulation. By increasing my bot locally from 0.1-0.2 seconds you see a win rate of 66%. You often see 2x increases without even using any of the Cython specific decorators.

I have a lot of experience in Python and while I can program / learn in other languages I would prefer if I could stay in the Python / Cython world. As a more hobby programmer it takes a long time to gain fluency in a language.

Has Cython been consider?
Would you consider Cython?
Can I write if for you?

! I do not want this to devolve into a argument that python should just get more time. !
